SHE'S not even been in the house 24 hours yet, but Nancy Dell'Olio has already threatened to quit Celebrity Big Brother.

The former girlfriend of England football coach Sven Goran-Eriksson was the last of the 16 celebrities to enter the Elstree compound last night, but it seems she's feeling "quite disappointed" with the experience so far.

"I'm quite disappointed," the 54-year-old said during a discussion with ex-Ukip candidate and fellow contestant Winston McKenzie.
